Provided is a surface plasmon antenna that can be set so that the emitting position on the end surface of the plasmon antenna where near-field light is emitted is located sufficiently close to the end of a magnetic pole. The surface plasmon antenna comprises an edge having a portion for coupling with a light in a surface plasmon mode. The edge is provided for propagating surface plasmon excited by the light and extends from the portion to a near-field light generating end surface that emits near-field light. The edge for propagating surface plasmon is a very narrow propagation region. Therefore, the near-field light generating end surface, which appears as a polished surface processed through polishing in the manufacturing of the plasmon antenna, can be made a shape with a very small size, and further can be set so that surface plasmon propagates to reach the end surface reliably.

A thermally-assisted magnetic recording head is provided, in which a light source having sufficiently high output power for performing thermal-assist is disposed in the element-integration surface of the substrate to achieve improved mass-productivity. The head includes: a light source having a multilayered structure including a photonic-band layer and having a light-emitting surface opposed to the element-integration surface; a diffraction optical element that converges the emitted light; a light-path changer that changes the direction of the converged light; a waveguide that propagates the direction-changed light toward the opposed-to-medium surface; and a magnetic pole that generates write field. The surface-emitting type light source includes a photonic-band layer having a periodic structure in which a light from an active region resonates, and thus emits laser light on a quite different principle from a VCSEL. Therefore, the light source can be disposed in the element-integration surface, even though having sufficiently high output power.

When an economy switch signal is ON to instruct that fuel economy should be given priority, a blower of an air conditioning device is operated using a blower characteristic map for fuel economy so that a blower level of the air conditioning device is changed with respect to the change in an engine coolant temperature at a low rate. Also, it is determined whether an engine needs to be operated or stopped using an engine operation map for fuel economy so that the engine is likely to be stopped.

New heat treatable aluminum alloys having magnesium and zinc are disclosed. The new aluminum alloys generally contain 3.0-6.0 wt. % Mg, 2.5-5.0 wt. % Zn, where (wt. % Mg) / (wt. % Zn) is from 0.60 to 2.40.

An infusion fluid heating apparatus applicable to various types of infusion tube with different length dimensions includes a front-side tube fitting groove or a rear-side tube fitting groove formed on one of surfaces of a heating plate that receives an infusion tube in a first length between an inlet opening and an outlet opening open at the end surfaces of the heating plate. The groove also receives the infusion tube in a second length shorter than the first length. Therefore, the groove uses the second length for a relatively short infusion tube, capable of heating the tube appropriately and achieving high versatility. In addition, the tube fitting groove uses the first length for an infusion bag with a relatively long infusion tube, capable of heating the tube appropriately and increasing the maximum infusion fluid flow.

An object of the invention is to provide a roaster, the invention comprises a main container 10 equipped with the space in the inner portion; an upper supporter 20 including a flame hole 21 equipped at the side facing the bottom side of the main container 10, and a roasting plate supporting part 22 equipped at the circumference position of the flame hole 21, and is combined to the main container 10; a fuel vessel 30 which has a fuel filling part 32 is formed in the inner space and a spacer 34 equipped in the outer periphery position of the fuel filling part 32, and which is positioned in the main container 10 to be positioned at the opposite direction to the flame hole 21 of the upper supporter 20 and which is arranged as the state separated from the spacer 34.

There are provided a heater unit and a battery structure with heater, which are capable of heating the battery structure appropriately and preventing a heater (part or whole of the heater) itself from excessively increasing in temperature. A first heater unit is provided with a first sheet heater, a first holding member holding it, and a first sheet placed between a lower surface of a first heater and the first holding member in such a manner as to be deformable in at least a direction of thickness of the first heater. The first heater is deformed when the first heater unit is fixed to the battery pack 50, thereby pressing the lower surface of the first heater to bring an upper surface of the first heater into close contact with an outer surface (a surface to be heated) of a spaced part of the battery pack.
